Best way to clean old Cleaning valves?

[91CoupeMike]

Rebuilding my heads and was trying to clean a few valves and realized that chem dip, dispite having valves on the can and working flawlessly on Pistons" fails to work on hard carbon on the surface of the valves.

Any solutions? Bench grinder with a brass wheel?

Should I just drop them off the machine shop and have them clean them?

Brass wire wheel has always served me good

Try the Blue colored can of easy-off oven cleaner. It will not eat everything up.
Killer on carbs and brass jets and baked on hard carbon stuff....

Nah just cleaning the carbon (7k miles worth) off the valves. Not much. But they were new a few years ago.

Chuck them in a drill press and use some scotch brite pads on them.

Soak them in WD40 and then hit them with the brass wire wheel
